ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 769,741, dated September 13, 1904.

Application filed February 5, 1904. Serial No. 192,077. iNo model.)

To (07/ whom it may concern:

Be it known that I, ISAAC Q. GURNEE, acitizen of the United States, residing at Butler, in the county of Morris and State of New J ersey, have invented certain new and useful Improvements in Atomizers, of which the following is a specification.

This invention relates to atoinizers or to such apparatus as are adapted for spraying or the application of vapor, gases, medicated or purified air, or perfumes.

Heretofore hard-rubber atomizers with adjustable fluid-tube have been constructed with an outer tube or pipe fitted with an inner supply-pipe adjusted to a proper position, so as to produce the desired spray, and then both tubes are bent to the angle required after heating them, so as to soften the material. An atomizer so bent will not permit of the inner tube being removed unless it is first straightened out again to its original position. To hands inexperienced in handling hard rubber this is a very diiiicult matter, and in the attempt the inner tube is liable to change its position and the atomizer may become totally useless from a mechanical standpoint.

it is the object of the present invention to overcome this diiliculty in such way that bending is unncessary and also to construct the atomizer so that it may be placed in almost any temperature and will retain its original shape.

Another object of the invention is to produce an atomizer particularly adapted for perfumery on account of its compact form and non-corrosiveness.

My invention consists of certain features of construction and combinations of parts to be hereinafter described, and then claimed, with reference to the accompanying drawings, showing a desirable form of my invention, and in which Figure l is a side elevation of my improved atomizer, the receptacle for the liquid-as, for instance, a bottlebeing indicated by dotted lines and a portion of the rubber tube leading from the air-supply bulb being shown as broken away. Fig. 2 is a longitudinal section of the atomizing features of the invention, and Fig. 3 is a transverse section, enlarged, on the line 3 3 of Fig. 2.

Referring now to the drawings, the bottle or other liquid-receptacle a may be of any suitable shape or design and may be provided with a plug or stopper, to which the atomizing instrumentalities may be applied, or the latter may be applied in any other well-known manner, as by a cap, which is screwed onto a screwneck bottle. The air-bulb (not shown) has its tube 7) applied in a well-known manner onto a nipple 0 of a head (7, which head is provided with an enlarged base (1', which in the type of the invention shown in the drawings rests directly upon the mouth of the bottle. The base of the head is furthermore provided with an eXternally-screw-threaded neclc (7 which may be screwed into a bottle-stopper. The airinlet 0 of the nipple c connects with a passage 0, which may be of the annular form shown or any other suitable form, and which passage is 7 formed between the inner wall of the hollow head (Z and its basal portions and a fluid-supply tubef', which dips into the fluid contained in the receptacle u in well-known manner. \Vithin the head and depending from its top is a chamber which at its lower end is provided with an axial intornally-serew-threaded opening into which is screwed the externally-screwthreaded upper end of the aforesaid fluid-supply pipef. Preferably formed at right angles to the opening g is another opening in the said chamber 5 which opening is also sere\ 'threaded and into which is screwed the externally-screw -threaded inner end of the fluid-tube h of the atomizing-nozzle It. The main body of the nozzle /1/ is screwed at its inner end into a suitable opening in the head diametrically opposite the air-inlet 0, although it is evident that this location is not essential. The outer end of the main body of the nozzle la. is externally screwthreaded to receive an internally-screw-threaded cap or tip 71 which is provided with a minute perforation or jet-orifice h said tip k with the outer end portions of it and h, forming a mixing-chamber if, in which is intermixed the gas and liquid before passing through the minute perforation or jet-orifice k in the form of a spray. The function of the tube It and cap k correspond substantially with the function of prior atomizers and will be clearly understood. To carry out the required function, the fluid-tube h is flattened at preferably two points, as c, (shown more clearly in Fig. 3,) the flats extending longitudinally of the said tube It, so as to form passages extending longitudinally of the atomizing-nozzle and connecting the passage 6 in the head with the chamber or space in the cap ]L2. The fluidtube It is substantially straightat least it is straight between its inner end and the part which passes through the opening g in the head-so that the said tube can be readily removed through said opening.

The liquid-supply pipe f is so inserted that it can be removed at any time and the atomizer thoroughly cleaned and the tube reinserted without in any wise interfering with the proper functioning of the instrument, and it can be of any desired length.

The adjustable inner tube h of the atomizing or nebulizing portion of the instrument can be regulated in evident manner to give a coarse or dry spray by turning it either to the right or left until the desired spray adjustment is produced. The fluid-tube h being substantially straight permits the described adjustment to obtain the desired purpose in an effective manner.

The screw connections may evidently be substituted by equivalent means, and it is not abspollutely essential that the tubes be adjusta e.

Applied to the top of the head (Z of the atomizer which is shown in the drawings, although not essential, is a small plug j, which can be removed for cleaning the apparatus.

Wherever the words separate chamber appear in the claims it is to be understood that by the word separate a chamber is meant which is separate from the chamber formed by the hollow or cavity in the head.

Having thus described my invention and without limiting myself to details or enumerating equivalents, what I claim as new therein, and desire to secure by Letters Patent. is

1. In an atomizer, the combination of a head provided with an air-inlet, a fluid-supply tube between which and the head a downward annular air-passage is formed, and an atomizing portion or nozzle, the fiuid-tube of which is separate from said supply-tube.

2. In an atomizer, the combination of a head provided with an inlet for air, a fluid-supply tube between which and the head a downward annular air-passage is formed, and an atomizing-nozzle provided With an adjustable fluidtube.

3. In an atomizer, the combination of a chamber, the wall of which is provided with openings, a fluid-supply tube applied to one opening, an atomizing-nozzle provided with a single adjustable fluid-tube, said latter fluidtube being screwed directly into another of the said openings, and means for supplying suitable pressure to the atomizing portion or nozzle, for substantially the purposes set forth.

4. In an atomizer, the combination of a hollow head provided with an inlet for air, a separate chamber in the head, a fluid-supply tube connected adjustably with said chamber and between which and the head a downward pas sage leading from the air-inlet is formed, and an atomizing-nozzle having a fluid-tube connected with said chamber.

7. In an atomizer, the combination of a hollow head, a separate chamber depending from the top of the head, a fluid-supply tube connected with the lower end of said chamber, an atomizing-nozzle having a fluid-tube connected with the said chamber, and means for supplying pressure-air, for substantially the purposes set forth.

8. In an atomizer, the combination of a hollow head, the wall of which is provided with openings, said head being provided with an opening registering with one of the chambero'penings, a fluid-supply tube applied to the other opening of the chamber, an atomizing portion or nozzle provided with a single substantially straight removable fluid-tube applied to the said registering openings of the head and chamber and projecting through the head and chamber at right angles to the supply-tube, and means for supplying suitable pressure-airto the atomizing portion or nozzle, for substantially the purposes set forth.
